AUTOMATIC BOWLING PIN SETTING APPARATUS Joseph ram and William White, Newarh, N. r. Application July 21, 1942, Serial No. 451.104 '8 Claims. (01. 213-43) This invention relates to improvements in automatic pin setting apparatus for bowling alleys.

This invention has for an object to provide, in combination with a vertically movable pin spotter carriage means, a novel construction of cooperating means for automatically delivering pins to and distributively loading the same into said carriage means, preparatory to operation of the latter for depositing the pins upon the bowling alley in accurately spotted upstanding positions thereon, and properly grouped and spaced ready for play.

The invention has for another object to provide a novel pin distributing and loading means whereby pins delivered thereto are automatically distributed to and successively loaded into the several pin holder members of a pin setter carriag'e; said distributing and loading means comprising .an inclined chute or way including a succession of .dependent pin distributer drop wells which respectively terminate in means for discharging the-pins into the respective pin holder members of the pin setter carriage, each distributer drop well, except the last or lowermost of the series thereof, having movable deflector plate means for shunting a pin thereinto, together with means, actuated by a pin passing therethrough,

for moving its deflector plate means into the plane of the chute or way so as to bridge and close said drop well, whereby a succeeding pin descending the chute or way willpass over the closed drop well, and into the next succeeding drop well, and so on until a full set of pins has been loaded into the pin setter carriage. I

The invention has for another object to provide means for automatically restoring the distributer deflector plate means to normal initial upstanding open positions when the pin setter carriage is lowered and operated to set the pins can'ied thereby upon the bowling alley, thereby resetting the distributer means for repetition of its pin distributing and loading operations.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which:

Fig. 1 is a side elevation of the pin distributer .and loading means and the pin setter carriage as initially related and operated to load pins into said carriage, parts of said-carriage being shown in section; Fig. 2 is a plan view of the pin distributer and loading means, viewed in the direction of the arrow X in Fig. 1, but drawn on an enlarged scale Fig. 3 isa fragmentary longitudisetter carriage in plan, the section being taken on line 4-4 in Fig. 1; and Fig. 5 is a fragmentary horizontal section, taken on line 5-5 in Fig. 1, but drawn on an enlarged scale.

Fig. 6 is a view similar in part to that of Fig. 1, but showing the pin setter carriage lowered to pin setting position, and the means for restoring the distributer deflector plate means from drop well closing to normal initial upstanding drop well opening positions.

Similar characters of reference are employed in the hereinabove described views, to indicate corresponding parts.

In the drawings, the reference character Ill indicates the pin stand section of a bowling alley surface, and Ii the downwardly and rearwardly sloping pit at which said alley surfaceterminates. The reference character l2 indicates the ball and pin back-stop builer cushion which is usually suspended within the alley pit.

The pin spotter carriage. in an illustrative form thereof as shown, comprises a platform It having pin drop openings I4 therethrough, the grouping and spaced relation of which corresponds to the normal grouped positions of pins P when deposited and spotted on the pin stand section III of a bowling alley ready for play. Supported by said platform It, in axial alignment with the pin drop openings l4 thereof, are pin holder members, each comprising an upstanding receiving pocket element I5, which is preferably of inverted conical shape. Means are provided for opening and closing the bottoms of said receiving pocket elements I5 at proper times in accordance with operative movements of the spotter carriage.-

Such means is provided by slidable shutter plates l6 intermediate the bottom of said receiving pocket elements and the platform l3, said shutter plates having openings ll, adapted by movements thereof to be slid into and out of registration with the pin drop openings l4. Preferably these shutter plates is are aligned with rows of said pin drop openings I4 and associated receiving pocket elements It which are directed toward the rear end of the spotter carriage, and said shutter plates are slidably movable over the top surface of the platform I3, being guided by slideway guides i8 afllxed to the latter. The rearward ends of said shutter plates are coupled together by a cross-bar l8 common thereto, so that all move together when actuated; properly timed operative movements being imparted thereto by suitable actuating means. Preferably such actuating means comprises a solenoid 20 mounted on the rear end portion of said platform l3, the armature 2| of which is aillxed by a suitable supporting connection 22 to said cross-bar l9. Said solenoid 20, when energized, retracts the armature 2|, such movement of the latter operating to move said shutter plates l6 so as to register their openings l1 with and between the bottoms of the receiving pocket elements l and the platform pin drop openings i4, aligned therewith, so that pins P carried by the former may drop downwardly therefrom and through the latter for deposit in upstanding spotted position on the alley pin stand section III, when the spotter carriage is lowered to pin spotting position relative to said alley pin stand section. Suitably arranged spring means is provided for returning said shutter plates to successively disposed pin drop wells 32 corresponding in number to the number of pins P. viz. ten, which make up a full pin set to be stood upon the alley pin stand section III. The open top ends or mouths of said drop wells 32 lie in a plane substantially flush with plane of said fixed floor or bottom section 3| of the chute or way. Cooperating with the mouths of each drop well 32, except the last and lowermost thereof, are pivoted deflector-bridge plate members 33, each being affixed to a pivoting shaft 33 which is suitably iournaied, preferably in bearing portions 35 with which the upper end portion'of the forward wall of the associated drop well is provided. At least one end of each pivoting shaft 34 projects exteriorly of a chute side wall member 30, and terminates in a crank-arm 33, the

closed position relative to said receiving pocket elements and their associated platform pin. drop openings l4, when the solenoid is de-energized. An illustrative form and arrangement of said spring means comprises a compression spring 23 mounted around the solenoid armature 2| between the cross-bar connection thereto and the opposed end of.the solenoid 20.

Mounted on the underside of the pin setter carriage platform l3, in cooperative relation to the pin drop openings l4 thereof, are picker devices for handling and resetting standing pins which remain on the alley pin stand section It after a firstball is bowled, whereby to permit removal of dead wood preparatory to bowling of a second ball. These picker devices may be enclosed in a housing 24 afllxed to the underside of the carriage platform, in connection with which are provided'tubular pin discharge throats 25, through which the pins P pass for deposit upon the alley pin stand section III. These picker devices are not shown, but preferably comprise a construction and arrangement thereof such as fully described and illustrated in our copendin'g application for United States Letters Patent Serial No. 447,224, filed June 16, 1942.

The pin spotter carriage is mounted in any convenient manner for vertical up and down. movements, as, for example, in guides 26 in whic ride slide shoes 21, with which the sides of the platform i3 are equipped. Motion-may be imparted to the spotter carriage by suitably actuated lift chains, cables'or the like 28. Initially said spotter carriage is positioned in uplifted position (see Fig. 1), in which position the. shutter plates it are disposed in receiving pocket element closing position, so that plus? deposited in said pocket elements are held against downward movement through the platform pin drop openings l4 and discharge throats 25.

The means for delivering pins P to and distributively loading the same into the receiving pocket elements l5 of the spotter carriage, in an illustrative form thereof according to this invention, comprises a downwardly and forwardly wall members 30, which bound a chute or way tion of said chute or way, the same is provided with a fixed floor or bottom section 3|. Beyond said floor or bottom section 3| are a series of latter in turn terminating in an angular lift portion 31. Normally, said deflector-bridge plate members 33 are up-swung to standing position across the chute or way, so as to uncover and expose the mouth of an associated drop well 32, and in upward projection from the front wallof the latter so as to' deflect a pin P, sliding down the chute or way toward the same, into said drop well for passage therethrough.

Means are provided for releasabiy retaining said deflector-bridge plate members 33 in the normal up-swung positions described. As illustrativeiy shown, means for such purpose comprises supporting brackets 33 suitably ailixed-to the chute frame to project above and over the chute or way thereof, and afllxed to and supported by said brackets 33 are yieldable detent members 39 provided at their free ends with nosings 39' behind which the free ends of the upswung deflector-bridge plate members 33 are engaged, whereby to releasably hold the latter in normal up-standing positions.

Pin actuated means are provided for releasing and swinging down the deflector-bridge plate members 33 after a pin P enters and passes downwardly through an associated drop well 32. This means comprises a trip plate 40 pivotally connected withthe forward wall of each associated drop well 32, at a suitable pin intermediate the upper and lower end of the latter. The trip plate 40 of each said drop well is connected with its associated deflector-bridge plate member by a pull connection 4|, preferably comprising a chain, pull cord, cable or like flexible element. Each pull connection 4| is of such length that, when the served deflector-bridge Plate member '33 is up-swung to normal open position, the associated trip plate 40 will be up-swung to a normal position transverse to the pin passage of the drop well 32 within which it is mounted, and thus disposed to project into the path of pin movement therethrough. When a pin P is deflected by an up-swung deflector-bridge plate member 33, so as to be shunted into an associated drop well 32 for downward passage therethrough, said pin P, as it passes down through said drop well,will strike and swing down its trip plate, thereby exerting a downward pull upon the pull connection 4| thereof which is transmitted to the associated deflector-bridge plate member 33, whereby the latter is released from the yieldable detent member 39 and its nosing 33', and thereupon swung down to closing and bridging relation to the mouth of the drop well served thereby, thus permitting a succeeding pin P to pass thereover and to the next adjacent drop well. i

The last and lowermost drop well 32 requires arms.

. no pivoted deflector-bridge plate member since only the last pin P of a-set is passed therethrough, and consequently its mouth may. remain permanently open. The forward wail of said last and lowermost drop well 32 is provided however with'an extension 42 to project across the path of pin movement through the chute or way, so as to arrest a pin and turn it downward into and for movement through said last-drop Connected with the bottom ends of the drop wells 32 are pin conduits 43, the respective discharge ends of which are disposed in alignment with and above the respective pin receiving pocket elements I! of the spotter carriage; the preferred arrangement being such that pins P are successively delivered to said receiving pocket elements in reverse order, that is the conduit of the first and uppermost drop well 32 delivers a pin P to the ten pin position, the next to the nine pin position, the next to the eightpin position, and so on until the pin P passing through the conduit of the last and lowermost drop well 32 is delivered to the one or head pin position; all in conformance with the familiar standard group assesses in this pin receiving position, all of the defiectorbridge plate members 33 initially occupy their up-swung drop well opening positions ready to admit pins into said drop wells. Under these conditions, pins P which are thrown into the pit ll, move down to the rear of the latter, from which point theyare successively picked up by the pin carrierforks 45 of the elevator conveyer 44, so as to be carried upwardly from the pit to the receiving end of the distributer chute or way. Asa pin carrier fork 45 with -a pin P suspended thereon approaches the receiving end of the distributer chute or way, the ends of the pin discharge bar 41 of such pin carrier fork will ride 5 onto the oblique upwardly and outwardly inclined arrangement of pins when set upon a bowling alley.

Suitable means is provided for conveying pins P from the bowling alley pit H upwardly to and v for delivery into the upper end of the chute or way of the described pin distributing means. A

preferred arrangement and form of such pin conveyer means comprises a continuously operated endless conveyer chain 44, the rising course of which traverses the rear end of the-pit H, and

' extends upwardly therefrom to and somewhat 1 beyond the upper receiving end ofthe pin distributer chute or way. Afilxed to said conveyer chain 44, at suitably spaced intervals along the length thereof, are pin carrierforks 45, the arms of which are laterally spaced at a distance somewhat less than the major width of a pin P, so that when a pin P is engaged thereby itwill be suspended bottom up by and between said fork Each of the fork arms is provided with a longitudinal slot 46 of suitable length, the outer end of which terminates adjacent to the free end of the fork arm in which it is formed. Extending across the pin'receiving space intermediate said fork arms is a movable transverse pin discharge bar 41, the respective ends of which extend through the slots of the respective fork arms so as to project laterally and exteriorly therefrom, The pin discharge bar 41 of each carrier fork 45 is yieldably retracted by pull spring means 48 to.

an inwardly stopped position as determined by the rearward ends of the fork arm slots 46. Sup.- ported in a fixed position adjacent to the pin receiving end of the distributer chute or way,

. and respectively in the path of travel of the exteriorly projecting end portions of the carrier fork pin discharge bars 41, are suitably shaped actuating cam pieces 43 adapted to be engaged and traversed by said end portions of the pin discharge bars 41, whereby to move the latter outwardly in the fork armslots 46 so as to push a pin Poll of the carrierfork by which it is susmargins of the stationary cam pieces 49, and, as they transverse the latter, said pin discharge bar will bethrust outwardly, thereby pushing outward the suspended pin P, until finally said pin P is tumbled off of the carrier fork, bottom end first, onto the floor or bottom section 3| of the distributer chute or way (see Fig, 1). When thus deposited in the distributer chute or way, the pin P slides down through the same until it encounters the up-swung deflector-bridge plate member 33 of the first oruppermost drop well 32, being deflected thereby so as to drop bottom first thereinto. As the pin P passes downwardly through said first drop well, it encounters and swings down the trip plate thereof, thus in turn swinging down the deflector-bridge plate 33 to dispose the latter in closing and bridging relation to the mouth of said first drop well 32. In the meantime, the pin elevator conveyer means having carried a succeeding pin P to and discharged the same into the receiving end of the distributer chute or way, such succeeding pin will slide down the latter and over the closed deflector-bridge plate 33 of the first drop well, until, it encounters the up-swung deflectorbridge plate of the second drop well, whereby it is deflected downwardly through the latter, and so as to close its deflector-bridge plate. In this manner, each succeeding pin P delivered into the chute or way will move over drop wells through which previously delivered pins have passed to the next open drop well, and until finally a tenth or last pin is delivered to and passed through the last and lowermost drop well 32 which is constantly. open. Since each drop well is connected by its pin conduit 43 with a given and different pin receiving pocket element of the spotter carriage, the ten pins delivered through the chute or way and communicating drop wells will be properly distributed and loaded into the spotter carriage in the conventional grouped arrangement of a pin set-up for a bowling alley.

After the spotter carriage is loaded with a full complement of pins P, the same is actuated by suitably controlled and timed means (not shown) for lowering the same toward and adjacent to the alley pin stand section In, so that the pins P carried thereby may be released .and dropped therefrom upon the spots of the alley in stand section l0, and so as to stand upon said section ready for play- (see Fig. 6). An electrical circuit (not shown) to serve the solenoid 20 is provided, the same including control switch means which is preferably arranged to be automatically closed by arrival of the spotter carriage at'lts lowered pin setting position, thus energizing the solenoid 2|! at such time. The solenoid 20 being energized, functions to retract its armature II, the movement of which istransmitted to the shutter plates It, whereby to slide the latter to positions adapt- Means l'sprovided for resetting the deflector- I bridge plates 33 of the pin distributer means to open positions in which they are releasably retained by the detent members 38. This means comprisesa reset bar 50 which extends longitudinally beneath the lift portions 31 of the crank arms 33 which rotate the pivoting shafts 33 of said deflector-bridge plates. Said reset bar 50 is mounted for bodily up and down movement, and to this end longitudinally spaced lever arms ii are provided, to the free ends of which said reset bar is pivotally connected. Said lever arms 5! are pivotally mounted on bracket upports 52 which are affixed to a side wall 30 of the distributer chute frame. Said reset bar is normally and yieldably retained in lowered position, as determined by stops 53, b suitably anchored pull sp'ring elements 54 which are attached to said lever arms 5|. When said reset bar is caused to swing upward from its normal loweredposition, it engages the lift portions 31 ofdown-swung'crank arms 33. and by its upward movement up-swings the latter, thereby rotating the shafts-34 to in turn up-swing thev deflector-bridge plates 33 into detained engagement by the cooperating detent members 38 (see Fig. 6). I g

Means for effecting suitably timed actuation of said reset bar 50 is provided; Preferably such actuating means is timed to reset the deflectorbridge plates 33 while the spotter carriage is lowered to pin setting position, and thus prior to rise of the latter to raised position for reloading. Such'actuating means is subject to more or less variation in form and kind. Illustrative of a simple, effective and perhaps preferable form thereof, as shown by the drawings, the same com prises a bell-crank lever pivoted in bearing standard 55 afllxed on the platform I! Of the spotter carriage, in alignment with a shutter plate I! of the latter. The lower arm 56 of said bellcrank lever is connected by a link 51 to said shutter plate l6, and from the upper arm 58 of said the rise of the latter will operate to reset the deflector-bridge plates 33 .to open positions as above explained. When the shutter plates [3 are .closed saidbell-crank lever will be retumed'to normal initial position, the pull-cable 59 will be relaxed, and the reset bar 50 will thereupon be returned to lowered position by it springs 54, leaving the deflector-bridge plates 33 held in their 'open positions by the detent members 39. When the spotter carriage thereafter rises to its position for reloading with pins, the pull-cable .will

again slacken, and the distributor means is con-' ditioned for repetition of the above described pin distributing and loading operations. 1

We are aware that manyand various changes could be made in the construction and arrangement of the mechanisms and parts thereof which comprise the pin. setting apparatus above described without departing from the spirit of our invention and within the scope thereof as defined by the following claims. It is therefore intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. I,

We claim:
